摘要:
提出了一种非迭代分别检测时间序列图像间旋转、平移运动的方法.该方法基于傅立叶频谱的相位相关特性,解决了迭代配准算法中的旋转与平移耦合问题.通过精心选择参考图像,采用基于递归数字滤波的三次B样条插值方法,实现了功能磁共振序列图像的快速配准,配准精度达到了亚像素级.
Abstract:
A non-iterative method to determine the rotation and translation among the time-series images separately is presented, which is based on phase correlation properties of the Fourier spectrum, resolving the coupling problem of roto-translation in the iterative registration algorithm. In addition, by selecting the reference image exquisitely, using the cubic B-spline interpolation algorithm based on recursive digital filter, this method implements fast sub-pixel registration of fMRI time-series images.
